Admixture Calculator

Eurogenes K8 AMI

**Eurogenes K8 AMI** — An ancient-era admixture calculator focused on Europe. It models ancestry proportions across eight reference components (Euro_HG, LBK, South-Central_Asian, Siberian, Amerindian, Oceanian, Southeast Asian, Sub-Saharan) to provide a concise, interpretable snapshot of deep prehistoric affinities useful for researchers, genealogists, and enthusiasts.

About This Calculator

**Eurogenes K8 AMI — Ancient-era admixture calculator for Europe** This calculator estimates how an individual's DNA aligns with eight ancient and broad reference ancestries to produce a snapshot of **ancient-like genetic components across Europe**. It compares your genotype to proxies that reflect deep prehistoric and early historic population structure: **Amerindian, Siberian, Euro_HG (European Hunter-Gatherer), Oceanian, Sub-Saharan, Southeast_Asian, LBK (Early European Farmers), and South-Central_Asian**. Who this is for: - Researchers, archaeogeneticists, and students studying prehistoric population dynamics - Enthusiasts and genealogists interested in how modern or ancient samples relate to major ancient components - Anyone wanting a context-rich, ancestry-focused view tied to Eurasian prehistory What you learn: - Proportional contributions from hunter-gatherers, Neolithic farmers (LBK), potential steppe/central-Asian-like inputs (South-Central_Asian), and northern Eurasian signals (Siberian/Amerindian proxies) - Detection of minor extra-regional affinities (Oceanian, Southeast Asian, Sub-Saharan) that may reflect ancient gene flow, later migrations, or modeling noise - A concise, interpretable breakdown useful for comparing individuals, populations, and archaeological samples Genetic and historical context: - Euro_HG captures Western/Eastern hunter-gatherer ancestry; LBK stands for early Neolithic farmers who spread agriculture into Europe; South-Central_Asian and Siberian components can reflect Steppe and northern Eurasian affinities. Amerindian and Oceanian serve as distant proxies highlighting ancient northern or eastern connections, not direct claims of geographic migration. Why it's valuable: - Provides a reproducible, model-based framework to situate samples within broad ancient ancestries - Helps generate hypotheses about migration, admixture, and regional continuity Interpretation tips: - Components are model-dependent proxies, not absolute iden

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 8 carefully selected ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 8 reference populations
Ancient populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
